The example of a reaction to which Markovnikov's rule applies is: CH₂=CH-CH₂-CH₃ + HBr → CH₂Br-CH₂-CH₂-CH₃

In this reaction, the hydrogen atom from HBr adds to the carbon atom with the fewer alkyl substituents (less substituted carbon), while the bromine atom adds to the carbon atom with more alkyl substituents (more substituted carbon). This follows Markovnikov's rule, which states that in the addition of a protic acid (such as HBr) to an asymmetrically substituted alkene, the hydrogen atom adds to the less substituted carbon and the other atom adds to the more substituted carbon.

The smallest quantity is 600 centiliter and the largest is 600 kiloliter.

Answer:0

Explanation: zero because it is the most stable form of oxygen in its standard state

Answer:

First, we can find the partial pressure of carbon dioxide in the scuba tank by subtracting the sum of partial pressures of oxygen and nitrogen from the total pressure:

partial pressure of CO2 = total pressure - partial pressure of O2 - partial pressure of N2

partial pressure of CO2 = 3.33 atm - 1.20 atm - (unknown partial pressure of N2)

partial pressure of CO2 = 2.13 atm - (unknown partial pressure of N2)

Since the enhanced mixture only contains oxygen and nitrogen, the sum of their partial pressures should equal the total pressure:

partial pressure of O2 + partial pressure of N2 = total pressure

1.20 atm + partial pressure of N2 = 3.33 atm

partial pressure of N2 = 3.33 atm - 1.20 atm

partial pressure of N2 = 2.13 atm

Now we can substitute this value into the equation we found for the partial pressure of CO2:

partial pressure of CO2 = 2.13 atm - partial pressure of N2

partial pressure of CO2 = 2.13 atm - 0.77 atm

partial pressure of CO2 = 1.36 atm

Therefore, the partial pressure of nitrogen in the scuba tank is 0.77 atm.

The atom is a basic unit of matter, consisting of an atomic nucleus and a cloud of negatively charged electrons that surrounds it. The atomic nucleus consists of positively charged protons and neutrally charged neutrons (except in the atomic nucleus of Hydrogen-1, which has no neutrons).

The electrons in an atom are bound to the nucleus by electromagnetic forces. A collection of such atoms can also bond with each other, and form a molecule. Atoms containing the same number of protons and electrons are neutral, while those containing a different number of protons and electrons are positive or negative and are called ions. Atoms are grouped based on the number of protons and neutrons contained in the atomic nucleus. The number of protons in an atom determines the chemical element of that atom, and the number of neutrons determines the isotope of that element.

In this problem, we need to find the pH of a buffer (pH = 4.45) that is produced by the reaction of strong acids as HBr that reacts with weak bases as NaC₇H₅O₂ producing its weak acid and a salt, as follows:

HBr + NaC₇H₅O₂ → HC₇H₅O₂ + NaBr

If in the reaction, the limiting reactant is the strong acid, we will produce a buffer (The aqueous mixture of a weak acid and its strong base).

Using Henderson-Hasselbalch equation, we can find the pH of this buffer:

\(pH = pKa + log \frac{[NaC_7H_5O_2]}{[HC_7H_5O_2]}\)

Where:

pKa is -log Ka = 4.20

[] could be taken as the moles of each species

After the reaction, the moles of HBr = Moles of HC₇H₅O₂ and the remaining moles of NaC₇H₅O₂ = Initial moles of NaC₇H₅O₂ - Moles of HBr.

Moles HBr:

22.5mL = 0.0225L * (0.200mol/L) = 4.5x10⁻³ moles HBr

Moles NaC₇H₅O₂:

50.0mL = 0.0500L * (0.250mol/L) = 0.0125 moles NaC₇H₅O₂

That means the moles after the reaction of the species of the buffer are:

Moles HC₇H₅O₂ = Moles HBr = 4.5x10⁻³ moles

Moles NaC₇H₅O₂ = 0.0125 moles - 4.5x10⁻³ moles = 8.0x10⁻³ moles

Ther are two things that define wheter a molecule is polar or not polar. First we have to decide if the bonds are simetrical or asimetrical. Simetrical bonds only occur when they are inbetwen two equal atoms. This is not the case since we have two bonds: K-S-K. The next step is to identify the structure of the molecule, because asimetrical bonds in oposite directions will calcel each other out. So lets see the structure of this molecule:

Sulfur atom needs 8 electrons to be stable. Sulfur has 2 electrons for each K-S bond. So we have 4 there. we need 4 more. They are in 2 unbonded orbitals. 2 electrons in each orbital. The repulsion forces between unbonded orbitals are grater than bonded orbitals. This causes the molecule to form and angle and therefore the polarity of the asimetric bonds do not cancel each other which means we have a polar molecule. This is the very same process that hapens to the water molecule

Answer:

The correct answer I think is Wilting of Seeds

Explanation:

salinization is when the water evaporates and leaves behind the salt in the water. Which causes the seed to whither because salt sits in its roots, and leaves no way for any more water to get in. So it makes it hard for seedling so get water.  

I think that is correct! Hope its right

A sign of salinization in crop plants is Wilting of seedlings. Thus the correct option is B.

Increased salt percentage in the soil is known as salinization, and it is brought on by soluble substances in the water supply. The land may be flooded by seawater or saline groundwater flowing through the soil downward, depending on the source of the water.

Due to the poor plant growth circumstances caused by salinity, the ground surface is constantly moist and lacks vegetation. Lands become very prone to erosion as a consequence. The amount of salt on the soil's surface rises as a result of excessive irrigation owing to evaporation.

Saline soils cause crops to suffer because of high salinity stress, nutritional problems and toxins, poor soil physical conditions, and decreased agricultural output.

Therefore, option B is appropriate.

From the reaction of 74.2 g of N2 and 14.0 moles of H2, approximately 3.18 x 10^24 molecules of NH3 can be produced.

To determine how many molecules of NH3 can be produced from the reaction of 74.2 g of N2 and 14.0 moles of H2, we need to use the balanced chemical equation for the reaction:

N2 + 3H2 -> 2NH3

First, let's convert the mass of N2 to moles. The molar mass of N2 is 28.02 g/mol, so:

74.2 g N2 * (1 mol N2/28.02 g N2) = 2.64 mol N2

Next, we need to determine the limiting reactant. To do this, we compare the moles of N2 and H2 in a 1:3 ratio. Since there are 2.64 moles of N2 and 14.0 moles of H2, we divide the moles of each reactant by their respective coefficients in the balanced equation:

2.64 mol N2 / 1 = 2.64
14.0 mol H2 / 3 = 4.67

The mole ratio tells us that for every 1 mole of N2, we need 3 moles of H2. Since we have more moles of H2 (4.67) than moles of N2 (2.64), H2 is in excess, and N2 is the limiting reactant.

Now we can calculate the moles of NH3 produced. According to the balanced equation, 1 mole of N2 produces 2 moles of NH3. So:

2.64 mol N2 * (2 mol NH3/1 mol N2) = 5.28 mol NH3

Finally, we can convert moles of NH3 to molecules. Avogadro's number tells us that 1 mole of any substance contains 6.022 x 10^23 molecules. Therefore:

5.28 mol NH3 * (6.022 x 10^23 molecules NH3/1 mol NH3) = 3.18 x 10^24 molecules NH3

Therefore, from the reaction of 74.2 g of N2 and 14.0 moles of H2, approximately 3.18 x 10^24 molecules of NH3 can be produced.

Answer:

Molecular formula => C₃H₈O₃

Explanation:

From the question given above, the following data were obtained:

Carbon (C) = 39.12%

Hydrogen (H) = 8.75%

Oxygen (O) = 51.12%

Molar mass of compound = 92.09 g/mol

Molecular formula =?

Next, we shall determine the empirical formula of the compound. This can be obtained as follow:

C = 39.12%

H = 8.75%

O = 51.12%

Divide by their molar mass

C = 39.12 / 12 = 3.26

H = 8.75 / 1 = 8.75

O = 51.12 / 16 = 3.195

Divide by the smallest

C = 3.26 / 3.195 = 1

H = 8.75 / 3.195 = 2.7

O = 3.195 / 3.195 = 1

Thus, the empirical formula is CH₂.₇O

Finally, we shall determine the molecular formula of the compound. This can be obtained as follow:

Empirical formula = CH₂.₇O

Molar mass of compound = 92.09 g/mol

Molecular formula =?

Molecular formula = Empirical formula × n

Molecular formula = [CH₂.₇O]ₙ

92.09 = [12 + (2.7×1) + 16] × n

92.09 = 30.7n

Divide both side by 30.7

n = 92.09 / 30.7

n = 3

Molecular formula = [CH₂.₇O]ₙ

Molecular formula = [CH₂.₇O]₃

Molecular formula = C₃H₈O₃

In the electrophilic aromatic substitution reaction between benzaldehyde and Br2 in the presence of FeBr3, the first step involves the generation of a carbocation intermediate. This carbocation is formed when the bromine molecule attacks the benzene ring, displacing a proton.

Since benzaldehyde is a meta-director, the carbocation intermediate will be stabilized through resonance. The resonance structures can be represented as follows:

Structure 1:

      Br

       |

Ph-C(+)-H

       |

Structure 2:

      Br

Ph-C-H

  |    |

  +    Ph

Structure 3:

      Br

       |

Ph-C-H

  |    |

Ph    +

In these resonance structures, the positive charge of the carbocation is delocalized throughout the benzene ring. The presence of the electron-withdrawing aldehyde group (CHO) in benzaldehyde directs the incoming bromine atom to the meta position relative to the aldehyde group.
